Cleanup standards and field guidance
for environmental professionals.
Currently covering Ohio, Indiana, and national programs - with more states on the way. Every value cited to its primary regulatory source and verification-dated.
Why SiteRef?
State agency cleanup standards are buried across dozens of PDFs, scattered database tools, and rule appendices that change without notice. SiteRef pulls them into one place - cited to OAC rules, IDEM Published Level tables, and CIDARS dates - so you can find the value you need without an hour of setup work.
Quick Start
Ohio
VAP, BUSTR, and DERR cleanup programs. CIDARS standards for soil, groundwater, and air.
Indiana
VRP, SCP, LUST, and Brownfields programs. IDEM R2 published levels for all media.
